Re: Text on HP 67/97's Message #13 Posted by Rafa on 14 Oct 2001, 11:05 a.m., in response to message #12 by Robert Blaschke
Hello Robert,
I own a HP-67 since not very long. After reading your message and the article from Wlodek Mier-Jedrzejowicz I have tried moving the battery of my 67. Since the battery pack I have is 100% hand made it hasn't been difficult to short-circuit the calculator momentarily. I couldn't produce strange program instructions but after several atempts I've been able to produce these NNN numbers:
-0.440600000_IC
and
-0.66_______---
(the underline ___ means only blank display, not a dash)
the intersting thing is that I've been able to produce this second number twice so it could mean that their production could possibly be controled (with the apropiate technique --phase boxes, etc.)
I could store them in registers as if they where normal numbers, but as my battery pack was almost discharged I couldn't save them onto a mag card.
Who knows, perhaps some kind of PC program could be designed one day to transfer information between the HP-67 and the PC via the 67 power supply.
